Question

What is the area of a circle with a diameter of 14

Answer 1

Answer:
Area = πr^2
So A=π(14\2)^2
A=π49
A=153.94 ( 2 decimal points)

Answer 2

I THINK

it's 1436.8

Explanation:

btw this symbol is multiply -> •

v = 4/3π • r3 ( the 3 is supposed to be small-)

v = 4/3π • ( 7 )3

1436.75 round

v = 1436.8
